An aircraft catapult is a device used to help fixed-wing aircraft gain enough airspeed and lift for takeoff from a limited distance, typically from the deck of a ship. They are usually used on aircraft carrier flight decks as a form of assisted takeoff , but can also be installed on land-based runways , although this is rare.
The Electromagnetic Aircraft Launch System (EMALS) is a type of electromagnetic catapult system developed by General Atomics for the United States Navy. The system launches carrier-based aircraft by means of a catapult employing a linear induction motor rather than the conventional steam piston , providing greater precision and faster recharge ...
Carrier operations changed after the second world war to include radar-assisted night operations [17] and accommodate jet aircraft requiring catapults. Helicopters, V/STOL aircraft, and widespread adoption of angled flight decks simplified simultaneous launch and recovery of aircraft. Infrequency of combat between equivalent opposing air forces ...
This roughly 10° check turn is made to increase separation of (nearly) simultaneously launched aircraft from the waist/bow catapults. After the clearing turn, aircraft proceed straight ahead paralleling the ship's course at 500 feet (150 m) until 7 nautical miles (13 km; 8.1 mi). Aircraft are then cleared to climb unrestricted in visual ...

An electromagnetic catapult, also called EMALS ("electromagnetic aircraft launch system") after the specific US system, is a type of aircraft launching system. Currently, only the United States and China have successfully developed it, and it is installed on the Gerald R. Ford-class aircraft carriers and the Chinese aircraft carrier Fujian.
The ship reached 100% complete on 11 July 2019 with the installation of the upper bow and launch deck consisting of the ship's two forward catapults. [22] On 1 October 2019, the ship's crew was activated for the first time as Pre-Commissioning Unit (PCU) John F. Kennedy at a ceremony aboard the vessel at Newport News Shipbuilding. [23]
The Type 004 aircraft carrier is a planned supercarrier of the People's Liberation Army Navy's aircraft carrier programme.Like the Type 003 aircraft carrier (Fujian) it will feature an integrated electric propulsion system that will allow the operation of electromagnetic catapults.
